     ALEXANDRIA, Va., July 23 -- Dan C. Lyman of Cincinnati has developed a warranty compliance validation method.
     According to the U.S. Patent & Trademark Office: "A method for validating warranty compliance for compatible fluid use of a printing system entails fluidly engaging a replaceable fluid container with a print station. The container includes a smart card adapted to track volumetric credits. Through use, the print station requests that fluid be added to a reservoir from the container."
     An abstract of the invention, released by the Patent Office, said: "The method continues by ascertaining the presence of the smart card in the reader/writer and reading the smart card to obtain information related to the fluid. The print station operates per the information from the smart card. The method ends by ascertaining the amount of fluid amount removed from the container and writing the withdrawn amount to the smart card as a debit, thereby maintaining printhead operation under warranty."
     The inventor was issued U.S. Patent No. 7,401,052 on July 15.
     The patent has been assigned to Eastman Kodak Co., Rochester, N.Y.
     The original application was filed on May 5, 2004, and is available at:,401,052.PN.&OS=PN/7,401,052&RS=PN/7,401,052.
